A diet filled with nutrient-rich foods can be a game-changer for your brain, improving your decision-making and problem-solving skills, as well as sharpening your focus and boosting your memory, explains Matthew Kuchan, Ph.D., lead scientist and resident nutrition and brain health expert at Abbott, a global healthcare company located in North Chicago.

We asked experts to dish on the best foods for our brains. Here are their nine top recommendations.

1. Leafy green vegetables

To be more precise, zone in on dark green veggies like broccoli, cabbage and kale, according to Registered Dietitians Kerry Clifford and Meghan Daw, who work with Fresh Thyme Farmers Market. These foods contain carotenoids and flavonoids, antioxidants that help promote brain function, memory and attentiveness, they explain. You can make a cabbage or broccoli slaw as a side dish to sneak more of these leafy greens into your family’s diet, suggests Clifford, also the 2017 vice president for the Chicago Food and Nutrition Network.

2. Eggs

Two nutrients that combine and act as a superhero duo? Lutein and zeaxanthin. These nutrients can help improve your memory at any age, according to Kuchan’s research, which he conducts through the Center for Nutrition, Learning and Memory, a partnership between Abbott and the University of Illinois at Urbana-Champaign. Among the studies that have come out of the partnership is one that shows seniors who consume more lutein are better able to retain and use information they’ve acquired throughout life. Lutein and zeaxanthin are especially prevalent in those leafy green veggies that we already touched on (yet, another reason to get another serving of those collards or spinach), but you can also find them in eggs.

3. Seafood

Maybe you do a #MeatlessMonday. How about preceding it with a #SeafoodSunday? Specifically, anchovies, herring, mackerel, Pacific oysters, sablefish, salmon, sardines, swordfish and trout are the best types of seafood for your brain because they’re especially rich in omega-3s.

Vannice says a significant body of evidence shows omega-3 can be a boon for memory, fighting depression and even reducing headaches. Omega-3 fatty acids EPA and DHA are healthy, essential fats that naturally occur in seafood. DHA, Vannice explains, is essential in infant development. She points to a study that found toddlers whose mothers had higher DHA blood levels at delivery were able to maintain better focus when compared to their peers whose mothers had lower DHA levels. Another study shows that teenagers who consume omega-3s have less anxiety before tests, Vannice says. “People who eat fish over their lifetime have better cognitive function as they age,” she says.

Megan Casper, a registered dietitian nutritionist and writer for Nourished Bite, says salmon is one of the best sources for long-chain omega-3 fatty acids, EPA and DHA. “These fats are considered essential, since your body can’t make them, and they’re linked to all sorts of amazing health benefits,” she says. “Diets high in EPA and DHA can decrease inflammation and oxidation in the brain, which helps reduce memory loss as well as anxiety and depression.”

4. Nuts and seeds

Both nuts and seeds are great sources of vitamin E, says Rene Ficek, a registered dietitian nutritionist and the lead nutrition expert for Seattle Sutton’s Healthy Eating. Research has found that higher levels of vitamin E correspond with less cognitive decline as you age, Ficek says. But an important reminder: Nuts and seeds are high in calories, so portion control should be exercised, she says. She recommends an ounce a day of walnuts, hazelnuts, Brazil nuts, filberts, almonds, cashews, peanuts, sunflower seeds, sesame seeds, flax seed or un-hydrogenated nut butters — all of which will give you enough vitamin E (We love Niloofar Persian Trail Mix, which is packed with cashews, almonds and walnuts). As an added bonus, nuts are a natural mood booster, Ficek says.

5. Tomatoes

Evidence suggests lycopene, a powerful antioxidant found in tomatoes, could help protect against the kind of free radical damage to cells that occurs in the development of dementia, particularly Alzheimer’s, says Ficek.

“Keep in mind that the lycopene found in tomatoes is only available to our bodies if tomatoes are cooked,” she says.

A recent study showed the MIND diet lowered the risk of Alzheimer’s by as much as 53 percent in those who followed it closely and by about 35 percent in those who followed it moderately.

But when it comes to fighting off Alzheimer’s and other dementias, make sure you don’t stop at healthy eating. Regular exercise is another critical component.

“Research suggests that regular physical activity can reduce the risk of cognitive decline,” says Melissa Tucker, director of the helpline and support services at the Alzheimer’s Association Illinois Chapter. “Exercise appears to play a role in protecting the brain from Alzheimer’s disease and other dementias, and also in living better with the disease if you have it.”
